Issue/Introduction
The Out Of The Box Dashboard Health Monitoring : Connector Health, is not updating with DX UIM stats in the Volume section.
After a certain point in time, it stopped showing data for Metrics and Alarms, particularly for the Added Count. It occurred only for the UIM Connectors.
The probe apm_bridge had no issues, all new entities and groups were correctly showed in the dashboard.
No issues with the APM OI Connector either, neither in terms of entities, alarms, or metrics.
Environment
DX Platform 24.2
DX UIM 23.4.x
oi_connector 2.01
apm_bridge 2.01
Cause
There were missing OI Conector metrics:
Triage--> Metrics by Inventory
--> UIM_OI_CONNECTOR_01
--> OI_CONNECTOR_01
--> DX_UIM
--> DX_UIM
-->Alarm
-->Metric
These are the metrics that the Volume section in the Health Connector Dashboard takes to populate the frames.
Resolution
Based on all the information gathered, we recommended the following changes:
- Set the configuration to NASS reactive client library and API . For some reason, the legacy library to connect to DX O2 via the NASS REST API was used.
The recommended value is:
enable_reactive_client = true
- Considering the high number of metrics sent by the oi_connector to the queue, recommended setting these values:
qos_bulk_size = 5000
qos_payload_bulk_size = 1000
- Considering the errors in oi_connector logs showing lack of active connections to the database, recommended increasing these values:
db_conn_min_pool_size = 10
db_conn_max_pool_size = 50
After the changes,perform a cold restart
- deactivate apm_bridge
- deactivate oi_connector
- activate apm_bridge
- activate oi_connector
The metrics should now be available in the dashboard.
